The effect of Lactobacillus spp. and coconut pulp extract on growth and health performances in Pacific white shrimp

The use of Lactobacillus sp as a probiotic has been widely reported to have a positive impact on shrimp cultivation. Coconut pulp is an industrial waste that could be used and has been reported to be a source of prebiotics. The use of prebiotics derived from coconut pulp extract in shrimp farming has not been widely used so there is still a lack of information regarding the dosage of synbiotics. The dosage of synbiotic administration can influence the success of the synbiotic application. This study aims to determine the optimal dose of synbiotics (probiotic Lactobacillus sp and prebiotic coconut dregs extract) to improve the growth and health of Pacific white shrimp (L. vannamei). The experimental design used was a completely randomized design (CRD). This research consisted of three treatments with three replications. Treatment 1 (addition of synbiotic dose 1), Treatment 2 (addition of synbiotic dose 2), and Treatment 3 (addition of synbiotic dose 3). The parameters observed were specific growth rate (SGR), feed conversion ratio (FCR), survival rate (SR), total hemocyte count (THC), differential haemocyte count (DHC), and water quality. This study showed results that were not significantly different in shrimp growth performances. However, THC and granulocyte cells showed significantly different.
